IMPROVEMENT IN MACHINES FOR CUTTING AND BLACKING THE WELTS lN BOOTS AND SHOES,

Specification forming part of Letters Patent No. 170,955, dated December 14, 1875; application filed J une 4, 1875.

To all whom it may concern:

Be it known that I, THOMAS K. KEITH, of Haverhill, in the county of Essex and State of Massachusetts, have invented a new and Improved Machine for Cutting and Blacking the Welts in Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the accompanying illustration, Figure 1 is a perspective view of my invention attached to a sewingmachine suitable for the purpose. A portion only of the sewing-machineis shown, it being no part of my invention. Fig. 2 is a plan view of my invention with the plate d removed. Fig. 3 is an enlarged transverse section of my device, upon the broken line w m. Fig. 4 is an enlarged plan of a portion of the device with the plate at removed. Fig. 5 is an enlarged sectional view of the inking or blacking apparatus.

Similar letters of reference indicate corresponding parts.

a represents certain portions of a suitable sewing-machine, which sews the welt into the upper, making a seam. a is the feed of the sewing-machine. b b is a plate, from which extends the plate 0, which, after extending to a proper leng h, (say the length of a boot,) turns up and back, and forms the portion a. Projecting from the plate 0 are two plates, d and e, which are attached, respectively, to the upper and under sides. f is an additional feed, turning upon an arbor attached to plate I). Opposite the feed f, and fixed between plate (1 and 0, near the terminus of plate 0, is the knife 9, which cuts or takes out the welt.

The upper is placed in my machine with the welt between the plates 01 c, and the upper extending over and under them. The feed acarries it along to the knife 9, where, being pressed against it by the feed f, it is out or taken out by said knife, and comes out from between the plates at and e at the point where it strikes the edge of plate a.

h is a guide, held by the screw h, and capable of being adjusted as seen in Figs. 1 and 2. If desired, a wheel or feed may be substituted for it. It is a spring, placed upon the plate 6, and against the edge of plate 0. l is a box, pivoted at 0, and having an opening, m, in its upper side, and an opening, a, in the side or edge opposite to the guide h. This box and its openings are shown in Fig. 5. 0 is a blacking apparatus, hollow, supplied with blacking by means of pipe 17, and having an opening, 8, (see Fig. 5,) in its under side corresponding to the opening min box Z.

When not in use the box 1 is kept pressed out into the position shown in Figs. 2, 4, and 5, by means of the spring 70. In this position, as will be seen by reference to Fig. 5, the openings s and m do not meet, and therefore no lglacking can pass from the apparatus 0 to the ox l.

Now, when the upper and welt have passed through the cutting operation above described, by means of which the welt is taken out, the said upper and the remaining portion of the welt pass along until they reach the guide h. When they arrive at the guide, in passing between it and the projecting edge of the box I, the said box I is pressed back until the opening m is opposite or under the opening .9 in the blacking apparatus. The blacking then passes through the two openings into the box I, and through the openings n upon the welt, thoroughly blacking it.

The amount or flow of blacking can be easily regulated by turning the cam t, which would operate upon the apparatus 0 so as to prevent the openings from coming exactly opposite each other. The welt is now out and blackened in a thorough and workmanlike manner.

It will readily be seen that the plate 0, by bending over into the shape seen in the drawing, forming the plate 0, and having the plates cl and reattached, forms a spring pressin g toward the feed f, thus keeping the work tightly in its proper place.

In practical operation the welt is cut, blackened, set up, and the seam rubbed down with a single passage through the machine.

Having thus fully described my invention,

what 1 claim, and desire to secure by Letters Patent, is-

1. The combination, with the feed f, of the knife 9 and spring-plates d e, substantially as 3. The combination of the, device Z, m, n,

and for the purpose described. with the. spring is, substantially as and for 2. The combination of the blacking appathe purpose hereinbefore set forth.
